Welded Steel Pipe (Water and Gas Supply) DN, EN 10255

Buy Water and Gas Pipes at Competitive Prices

UTMK provides comprehensive supplies of steel water and gas pipes (WGP) compliant with EN 10255 and ISO 65 (GOST 3262-75). Our inventory features high-quality construction steel grades such as S195T and S235JR with nominal diameters (DN) ranging from 6 to 150 mm. We ensure strict quality control, provide precision cutting services, and manage efficient logistics with delivery across the EU or self-pickup from our regional distribution centers in Poland and Bulgaria.

Technical conditions for the production of WGP pipes are strictly regulated. The standards apply to welded steel pipes—available in both black and galvanized finishes. The latter offer superior corrosion resistance, though their mass is approximately 3% higher than that of non-galvanized counterparts. Products are classified by wall thickness into light, ordinary (medium), and reinforced (heavy) series, which determines their capacity to withstand internal pressure within engineering systems.

Technical Parameters and Tolerances according to EN 10255 (GOST 3262-75)

In accordance with industry regulations, weight deviations for finished products must not exceed +8%. Pipes are supplied in lengths from 4 to 12 meters (available in both fixed and random lengths). A critical performance characteristic is the hydraulic test pressure, which confirms the integrity of the weld seam and the overall metal structure:

• Light and Ordinary pipes: withstand pressures up to 2.4 MPa (25 kgf/cm²).
• Reinforced pipes: rated for heavy-duty loads up to 3.1 MPa (32 kgf/cm²).

For industrial infrastructure and technical projects, UTMK ensures ESG compliance and ISO-certified quality. Beyond standard WGP, we provide Hot-Rolled ERW Pipe and high-pressure Seamless Boiler Tube for complex systems. To complete your installation, we supply Pipe Reducer components. For enhanced durability in corrosive environments, consider our Galvanized Welded Water & Gas Pipe or high-grade Matte Finish Stainless Pipe with expert cutting and bending services.
